Mr. Herbert H. Smith is an experienced naturalist wh 
Si Vineet 1 for purposes of entomological research, and Suet M. 
attaches to his opinion. A 
_ From Grenada Mr. G. W. Smith reports (20)— 
* ]st. There is an. old and well-known pest (Diatrea saccharalis) 
found in the diseased fields one with the beetle. 
* 2nd. Out of over 100 examples I have taken from a diseased field 
I haye never found the beetle in canes that had not. been previously. 
attacked by the larger ‘ borer,’ . , but on the contrary, I found 
numberless instances of canes, where the devastation done by the * borer? 
(larva of the moth) was present, in rper canes there is not a trace 
of the beetle. These examples I am not satisfied with, and shall con- 
tinue to collect until I have about "400 good canes, when I should say 
the evidence would be conclusive, viz., tht the beetle is one of the 
sequele’ to the Nib of the moth "borgo; and not the real 
destroyer of the ca: d

“J have secured about 30 specimens [of canes containing moth larvz] ; : 
it is remarkable that in all XS 30 specimens where the larve of the, 
moth is va at work, there is no sign of the beetle (except in one 
specimen two small holes: and there the moth is in the pupa stage), and 
the cane is Withare and pres 
Trinidad and elsewhere.

eo Wels to the ravages of the moth-borer, the juice of the cane has 
become sour, and acquires a distinct smell. The beetles are then drawn | 
to it (to feed on their natural food), and hence their presence in such | 
numbers in diseased canes. have also taken a spécimen of soun 
cane in which there was no trace of eithen moth or beetle, pounded 
so as to rupture all the tissues, and flung it aside, away fon any oa 
field ; after some time these same ete me e found n it, hence 
.. The latter remarks point to megass being ve ry attractive while 
mum this has been observed by the ced Committee e (26). 
Mr. G. W. Smith writes later (21) :— - ' 
.* I haye further to report that a ew -— ago I received eight. su 
. canes from Barbados. On examining them I found the small bee beetle, 





| perforans, to be the same as that attacking island, bu 
. . addition I found in three of them the tracks of a much larger beetle |

“Twas able to secure three nest s,and in two of them I found the 
perfect. insect, which I send in a bottle of alcohol, together with th 
hich it was found; also a piece of sugar-cane showing the 
nad e by it; this closely resembles that of the moth-borer, but l 
E have M yet found Su d in Grenada." — 
This horus sacchari, qu 
eevil Sphenop 
was partly responsible for the larger burrows in the canes
